'While this gesture has been part of French culture for many years, it was not until recently that I learned of the very negative concerns associated with it,' Parker said in a statement.

'When l was photographed making that gesture three years ago, I thought it was part of a comedy act and did not know that it could be in any way offensive or harmful,' the 31-year-old added. 'Since I have been made aware of the seriousness of this gesture, I will certainly never repeat the gesture and sincerely apologize for any misunderstanding or harm relating to my actions.

'Hopefully this incident will serve to educate others that we need to be more aware that things that may seem innocuous can actually have a history of hate and hurt.'

The 'quenelle', which is performed by holding one arm straight by the side while touching that arm's shoulder with the opposite hand, has been labelled a reverse Nazi salute.

The salute has been made popular by Dieudonne, who is a well-known actor, comedian and political figure in France. Dieudonne said the gesture is a symbol of defiance.
